The National Weather Service's Pacific Tsunami Warning System released a hazardous wave alert for all coasts within 300 kilometers of the quake, a radius that includes much of Indonesia and the Philippines.
"Tsunami waves are possible for coasts located within 300km of the earthquake center," the warning reads.

There have been no immediate reports of casualties or damage from the Mindanao quake, which hit at a depth of 49km at 3:39 UTC on Saturday.
Government agencies have been advised to inform populations in coastal areas of the risk and to instruct them on relevant evacuation procedures, depending on the threat level. The islands of Geme and Tabukan Tengah (Indonesia) as well as Davao (Philippines) may experience tsunami waves within the hour. Davao City, on the southern Philippines island of Mindanao, is home to over 1.6 million people.
